This volume, which is part of the Clarendon Aristotle Series, offers a clear and faithful new translation of Books II to IV of Aristotle`s Nicomachean Ethics, accompanied by an analytical commentary focusing on philosophical issues. In Books II to IV, Aristotle gives his account of virtue of character in general and of the principal virtues individually, topics of central interest both to his ethical theory and to modern ethical theorists. Consequently major themes of the commentary are connections on the one hand with other relevant Aristotelian texts and on the other with modern writings, both text-related and thematic.
